Description
Geschossattrappe für Steilfenergeschütze. Die Erfindung betrifft eine Geschoss- attrappe für Steilfeuergeschütze und besteht darin, dass in sie ein kleinkalibriger Hilfs lauf und eine Druckluftkammer eingebaut sind, welche beide durch einen Abschiess- mechanismus miteinander in Verbindung ste hen.
In der Zeichnung ist eine der 81 mm Infanteriemine äusserlich vollkommen ent sprechende und gemäss der Erfindung ausge bildete Geschossattrappe in einer beispiels weisen Ausführungsform in einem Längs schnitt durch den Attrappenkörper darge stellt.
In die einer 81 mm Infanteriemine ent sprechende Geschossattrappe 1 ist der Hilfs lauf 2 eingeschraubt. In dem einen Teil des Attrappenmantels bildenden, dicht einge schraubten Boden 3 befindet sich am vordern Ende ein Gewinde 20, in das die in die Ge- schossattrappe eingeschobene Pressluftflasche 21 eingeschraubt wird. Die aus der Flasche ausströmende Pressluft trifft auf den Kolben 11, der in einer Führung gleitend gelagert und mit einer Lederdichtung 13 versehen ist. Diese wird durch den konusartigen Kolben oberteil 14 und die Schraube 12 gehalten.
Der Kolbenoberteil besteht vorteilhaft aus Fiber oder einer andern elastischen Masse. Der Flaschenhals wird beim Einschrauben an den Kolbenoberteil angepresst und dadurch wird eine doppelte Dichtung erzielt. Der Kolben 11 wird durch die Feder 9 nach vorn gepresst und durch die Klauen 8 in der Schliesslage gehalten. Die Klauen 8 sind in den Gelenken 10 drehbar gelagert und kön nen in Ausnehmungen des Bodens<B>3</B> aus schwenken. Der Schlagstift 7 ist gleitend ge lagert und liegt mit der Spitze auf den In nenarmen der Klauen 8 auf.
Beim Auf schlagen des normalen Geschützschlagbolzens gegen den Schlagstift 7 drückt dieser auf die Klauen 8 und bringt sie zum Ausschwenken. Dadurch wird der Kolben 11 freigegeben und durch den Druck der Pressluft nach rück wärts geschleudert, wobei er ein im Boden 3 befindliches Überströmloch freigibt. Die Pressluft strömt nun durch das Überström- loch entlang der Wände der Pressluftflasche hinter das Hilfsgeschoss 15 und treibt dieses aus. Sodann wird der Kolben 11 wieder durch die Feder 9. ebenso wie die Klauen 8 und der Schlagstift 7 in die Ursprungslage zurückgebracht.
Es ist auch ohne weitere, möglich, an Stelle des gezeichneten auswechselbaren Pressluftbehälters die Pressluft in einer ent sprechenden Ausnehmung der Geschoss- attrappe selbst aufzuspeichern.
Bullet dummy for Steilfener guns. The invention relates to a dummy projectile for high-speed cannons and consists in the fact that a small-caliber auxiliary barrel and a compressed air chamber are built into it, both of which are connected to one another by a firing mechanism.
In the drawing is one of the 81 mm infantry mine outwardly completely ent speaking and according to the invention formed dummy bullet in an exemplary embodiment in a longitudinal section through the dummy body Darge presents.
The auxiliary barrel 2 is screwed into the dummy bullet 1 corresponding to an 81 mm infantry mine. In the tightly screwed-in base 3, which forms part of the dummy shell, there is a thread 20 at the front end into which the compressed air cylinder 21 pushed into the dummy bullet is screwed. The compressed air flowing out of the bottle hits the piston 11, which is slidably mounted in a guide and is provided with a leather seal 13. This is held by the cone-like piston upper part 14 and the screw 12.
The upper piston part is advantageously made of fiber or some other elastic mass. The bottle neck is pressed against the upper part of the piston when it is screwed in, thus creating a double seal. The piston 11 is pressed forward by the spring 9 and held in the closed position by the claws 8. The claws 8 are rotatably mounted in the joints 10 and can pivot out in recesses in the base 3. The striker 7 is slidably superimposed ge and rests with the tip on the In nenarmen of the claws 8 on.
When the normal gun firing pin hits the striker 7, this presses on the claws 8 and causes them to pivot. As a result, the piston 11 is released and thrown backwards by the pressure of the compressed air, whereby it releases an overflow hole located in the bottom 3. The compressed air now flows through the overflow hole along the walls of the compressed air cylinder behind the auxiliary projectile 15 and drives it out. The piston 11 is then returned to its original position by the spring 9, as are the claws 8 and the striker 7.
It is also possible without any further, instead of the replaceable compressed air container shown, to store the compressed air itself in a corresponding recess in the dummy bullet.
